It is not about proof (which, BTW, can be found by the very first Google link, and is quite mechanical and unexciting). Cut some trominoes (not triominoes, mind you) from cardboard paper and play with them for a while. Have fun. I mean, have fun the next time, because this time I'm going to claim the fun for myself.
